* ci: add PR-author and stale-issue inactivity workflows
Adds two queue-management automations:
- pr-author-inactivity: reminds PR authors after 72h of inactivity
following human reviewer/maintainer feedback (issue comments,
non-approval reviews, or inline review comments) and closes after
120h. Author response is detected via issue comments, inline review
replies, or commit/force-push events. Bot-authored reviews are
intentionally excluded so authors are not pressured by automated
nits alone.
- stale-issues: marks issues stale after 30 days of inactivity and
closes after a further 7 days. Exempts good first issue, help
wanted, and security labels. A pre-step also auto-applies
'exempt-from-stale' to issues opened by org members/owners/
collaborators, since actions/stale only supports label-based
exemptions. PR processing is disabled (handled by the workflow
above).
